Even then, different sources use different names for each of the layers. For this book, we will define five layers, as shown in Figure 1-12: application, transport, network, network access, and physical. Note that the layers do not specify precise protocols or exact services. In other words, the TCP/IP protocol suite does not tell us, for example, what kind of wire or what kind of connector to use to connect the pieces of a network. That choice is left to the designer or implementer of the system.

Figure 1-16 Sender and receiver communicating using the TCP/IP protocol suite Application Logical Connections Application Transport Transport Network Network Network Access Network Access Physical Sender Physical Physical Connection Receiver Notice the dashed lines between the sender’s and receiver’s application layers, transport layers, network layers, and network access layers. No data flows over these dashed lines. Each dashed line indicates a logical connection. A logical connection is a nonphysical connection between sender and receiver that allows an exchange of commands and responses.
